Answer:
Explanation:
Cross sectional area of post = 3.14 x(10.5)² x 10⁻⁴ = 346.18 x 10⁻⁴ m²
Weight = mg = 8300 x 9.8 = 8.134 x 10⁴ N
Stress = weight / area
= 8.134 x 10⁴ / (346.18 x 10⁻⁴)
23.49 x 10⁵ N / m²
Strain = stress / modulus of elasticity of steel
modulus of elasticity = 190 x 10⁹ Pa
strain = Stress \ young modulus
=
= 12.36 x 10⁻⁶
strain = change in length / original length
change in length = original length x strain
= 2.7 x 12.36 x 10⁻⁶
= 33.372 x 10⁻³ mm
.033 mm.
